Although Labor Day has come and gone and the fall semester has begun, summer is still in full swing at the Institute. This past Tuesday’s high temperature of 93°F (34°C) was the hottest temperature of the year so far in Boston. Strengthening offshore flow in advance of an approaching cold front will cause temperatures to flirt with the 90-degree mark once again today and tomorrow. The best chance for heat will come tomorrow afternoon, right before the cold front passes through. As the front arrives, expect thunderstorms to develop and move across New England tomorrow afternoon and evening. There is a chance that some of these storms could produce hail and/or damaging winds.
Temperatures will return to a more seasonable level after the cold front moves through, with temperatures returning to the mid 70s (°F) as high pressure takes hold for the beginning of next week.
Of course, the fall season doesn’t officially begin (astronomically speaking) until the equinox on the evening of September 22. So, even though school is back in session, don’t be surprised to see the occasional burst of summer in early September.
